HAY-WAGON BRAKE.

Specification of Letters Patent.

Patented July 28, 1908.

Application filed August 6, 1907. Serial No. 387,346.

To all whom it may concern:

Be it known that I, OWEN WOOTEN, a citizen of the United States, andresident of Pacific, Franklin county, Missouri, have invented certainnew and useful Improvements in Hay-Wagon Brakes, of which the followingis a specification containing a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a hay wagon brake, my object being to constructa simple, easily operatedbrake particularly adapted for use on haywagons, and the operating mechanism of which brake is arranged on theladder or frame at the front of the hay rack, thus providing brakingmeans which is readily accessible from the top of the load of hay.

A further object of my invention is to so apply the operating means ofthe brake to the ladder as that said ladder can be swung downward ontothe bed of the wagonv and still be in operative condition.

To the abovepurposes, my invention consists in certain novel featuresofconstruction and arrangement of parts, which will be-hereinafter morefully set forth, pointed out in the claims, and illustrated in theaccompanying drawings, in which Figure 1 is a plan view of a hay wagonwith a portion thereof broken away, and with my improved brake inposition on said wagon;

Fig. 2 is a section taken on the line 22 of Fig. 1, and showing theladder at the front of the frame elevated; Fig. 3 is a plan view of theupper end of the ladder, and showing a ratchet wheel applied thereto;Fig. 4 is a transverse section taken approximately, on the line 44 ofFig. 3, and showing the latch on the brake operating handle; Fig. 5 is adetail view of a detachable link used for connecting the cable to therockshaft of the brake, and which link is open; Fig. 6 is an elevationof the detachable link in a closed position.

Referring by numerals to the accompanying drawings :1 designates the bedor body of the wagon, 2 the side sills thereof, 3 the reach, 4 thehounds, and 5 the rear axle on the ends 'of which are arranged the rearwheels 6. 7

Fixed on top of the hounds 4 is a transverse beam 7, and supported fromthe ends thereof by short chains 8, or in any suitable manner, is abrake beam 9, on the ends of which are arranged shoes 10, which areadapted to engage the peripheries of the rear wheels. A retractile coilspring 11 is fixed at one end to one of the hounds 4, and at itsopposite end to the brake beam 9, the end of which coil spring normallymaintains the brake shoes 10 away from the wheels 6.

Journaled in bearings 12 on the under side of the hounds 4 is a rockshaft 13, which is provided with a pair of downwardly projecting arms14, to the lower ends of which are pivotally connected the rear ends-ofrods 15, tfie forward ends of which are connected to t e brake beam andthe right hand end of this rock shaft 13 is bent upward, as designatedby 16, and provided with an aperture 17. A connecting link comprises arod or strap 18, of resilient metal bent double, with one end providedwith an aperture 19, which is adapted to receive the laterally bent end20 of the opposite portion of the link and arranged to slide upon saidlink is a ring 21, which, when moved toward the free ends of the link,causes the same to move toward one another, with the laterally bent end20 seated in the aperture 19. This link forms a means of quickattachment or detachment with the upper end of the arm 16, and securedto the loop 22, at the forward end of the link, is the rear end of acable 23, which extends along the right hand side of the wagon bed 1.

Fixed to the sills 2, adjacent their forward ends, are bearings 24, inwhich is arranged for rotation a shaft 25, the right hand end of whichextends a short distance beyond the right hand bearing; and arranged towind on said extended end is a chain 26, the rear end of which isconnected to the forward end of the cable 23. The shaft 25 passesthrough the lower ends of the side rails 27 of the ladder .at theforward end of the hay frame, which ladder is provided with a transversebar 28 at a point near its center, and with a transverse top piece 29.Fixed on the transverse bar 28 is a bearing 30, with which is formedintegral a yoke 31; and formed integral with. said yoke are bearings 32,through which the shaft 25 passes. Fixed on the shaft 25, within theyoke, is a beveled gear wheel 33. Journaled in the bearing 30 is a shaft34, on the lower end of which, within the yoke 31, is fixed a beveledpinion 34" which meshes with the beveled gear wheel 33. Fixed on top ofthe transverse bar 29, at the top of the ladder, is a ratchet wheel 35,

in the center of which is formed a bearing 36, through which the upperend of the shaft 34 projects, and fixed on the upper end of said shaft34 is a crank handle'37.

The edge of the ratchet wheel is provided with a series of notches 38,and within each notch is formed a pair of shoulders 39, the same beingarranged on opposite sides of the opening into the notch. Fulcrumed onthe handle 37 is a pawl 40, the lower end of which is adapted to engagebehind the shoulders 39 in the notches 38; and pivotally connected tothe upper end of the pawl 40 is a link 41, the opposite end of which isconnected to the Y trigger 42, which latter is fulcrumed on the handle37, and there being an expansive coil spring 43 arranged behind saidtrigger 42. Arranged on the front edges of the side rails 27 of theladder is a transverse plate 44, which forms a driver's seat when theladder is swung downward out of use, and pivotally arranged on the innerfaces of the'side rails 27 are gravity legs 45, which support the ladderwhen the same is lowered.

The ladder is readily moved from one position to another; and, when ineither position,

the brake shoes 10 are applied to the rear wheels by engaging the crankhandle 37 and rotating the shaft 34, which by means of the beveledpinions and 34 imparts rotary motion to the shaft 25, thus winding thechain 26 on the extended end of said shaft, in turn rocking the shaft13, which action pulls the brake beam 9 rearwardly and causes the shoesto engage the rear wheels.

Should it be desired to lock the brake in its set position, the operatorpulls the trigger 42, which action throws the lower end of the awl intoone of the notches 38, and said ower end will engage behind one of thepair of shoulders 39 in said notch, thus holding the brake set. lVhenthe brake is released by loosening the pawl 40 from the notch in whichit has been engaged, the various operating parts of the mechanism willreturn to their normal positions, owing to the action of the coil spring11, which returns the brake beam 9 to its normal position. If desired, asheet metal hood may be provided on the yoke 31 so as to inclose thegearing and pre yent the same from becoming clogged with my A brake ofmy improved construction is easily applied for use, and can beconveniently operated when the ladder is in either elevated or loweredposition.

I claim v I 1. The combination with a hay wagon, of a shaft arranged forrotation at the forward end of the wagon frame, a ladder arranged toswing vertically on the shaft, a shaft ar ranged for rotation in theladder, a yoke journaled on the center of the first mentioned shaft, abearing formed in said yoke for the lower end of the shaft in theladder, meshing beveled pinions on the two shafts within the yoke, aratchet wheel fixed on top of the ladder, there being oppositelyarranged shoulders formed in the notches of the ratchet wheel, a crankhandle fixed on top of the shaft carried by the ladder, a pawl carriedby said crank handle and adapted to engage behind the shoulders in thenotches of the ratchet wheel, a brake beam arranged he neath the rearportion of the wagon frame, brake shoes on the ends of the beam forengaging the rear wheels of the wagon, a crank shaft j ournaled on theunder side of the wagon frame, connections between said crank shaft andthe brake beam, and a flexible connection from one end of the crankshaft to the end of the shaft journaled in the forward end of the wagonframe.

2. The combination with a hay wagon, of a brake arranged to engage therear wheels of said wagon, a shaft journaled for rotation in the forwardend of the wagon frame, a flexible connection between the shaft and thebrake, a ladder arranged to swing vertically on the shaft, a shaftarranged for rotation in the ladder, a yoke journaled on the center ofthefirst mentioned shaft in the wagon frame, and which yoke is rigidlyfixed to the ladder, a bearing formed in the yoke for the lower end ofthe shaft in the ladder, meshing bev eled pinions fixed on the twoshafts within the yoke, a ratchet wheel fixed. on top of the ladder,there being oppositely arranged shoulders formed in the notches of theratchet wheel, a crank handle fixed on top of the shaft carried by theladder, and a pawl carried by said crank handle and adapted to engagebehind the shoulders in the notches of the ratchet wheel.

In testimony whereof, I have signed my name to this specification, inpresence of two subscribing witnesses.
